THE future of medical implants may be fishy. A soft and fleshy electric eel-inspired battery could lie at the heart of next-generation pacemakers and other devices. To create a prototype of such a battery, Anirvan Guha at the University of Fribourg in Switzerland and his colleagues spread thousands of hydrogel bubbles across a thin, pliable surface. They then placed a second sheet of this material over the first, before finally filling the space between them with a saline solution. The ions in the salt water were enough to cause friction and generate electricity in the gel layers,
